WATER CLOSET.

SPECIFICATION forming part of Letters Patent No. 604,548, dated May 24,1898.

Application filed January 16, 1897. Serial No. 619,437. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, DAVID S. SCHUREMAN, a citizen of the United States,residing at Rockford, in the county of WVinnebago and State of Illinois,have invented certain new and useful Improvements in Water-Olosets, ofwhich the following is a specification.

The object of this invention is to construct a seat-action water-closettank wherein the tank can be secreted in the Wall or partition of thebuilding and be noiseless in its opera tion. It is a vertical tube inwhich a movable weight supported on the Water gives even and regularpressure to the water while being discharged into the bowl and a valvearrau gement whereby pressure on the free end of the seat conveys saidpressure to the valve-stein by abutting the rear end of seat against thevalvestem and thereby controlling the action of the water, also a seatfor the bowl supported independently of the bowl.

In the accompanying drawings, Figures, 1 and 2 are perspective views ofmy improve- Fig. 3 is a vertical view of the checkvalve. Figs. 4 and 5are perspective views of the bowl, seat, cover, and hinge connection.

Figs. 6, 7, and 8 are vertical sections through the tube and valveconnections.

A tube 1 is located in a vertical position, and at its upper end is ascrew-threaded cap 2, having an extension 3, its upper end being open.To the lower end of the tube is screwthreaded a casting consisting of avertical cylindrical tubular portion 4 and a horizontal tubular portion5, having an inlet-opening 6. A valve-seat is located Within thehorizontal tubular portion and consists of two heads 7 and 8, the formerbeing of less diameter than the latter, and seated in an annular recessWithin which is located a ring 9, of packing material. The head 8 hasits periphery screwthreaded, and the outer end of the horizontal portionis screw-threaded, receiving the head. These heads are connected by bars10, and the bars support a transverse valve-support 11. The head 7 has acentral opening 12, and its outer face supports a packing-ring 13. Theouter face of the head 8 is fitted to form a valve-seat, and the outerface of the open end of the tubular portion 5 has a flange 14. A cap 15has a flange 16, and a ring 17, of packing material, is placed betweenthe face of the flanges, which are held together by screws. This cap hasan annular space 18 i and an opening 19 formed therein.

. seat.

At the bottom thereof is formed a water-discharge 20. A screw-threadedextension 21 projects from the end of the cap and has a central opening.

The valve is automatic and closes with the pressure from the mains, andthe arrangement consists of a valve-stem 22, held supported by thesupport 11 and the extension 21.

To the end of the stem is secured avalve 23, and midway of its length issecured a valve 24. The extreme outer end of the valve-stem has areduced portion 25, and the larger end is screw-threaded, upon which isturned a nut 26. A spiral spring 27 for carrying the weight of the seatsurrounds the stem between the end of the extension 21 and nut 26. A cap28 has an opening in its end, through which the reduced portion of thevalve-stem projects, its open end having a screw-threaded connectionwith the extension 21.

The valve 23 is adapted to close the hole 12 in the head 7 and the valve24 to close the opening 29 in the head 8, having its inner face providedwith a packing-ring 30. A pipe 31 has a connection with chamber 32through the opening 6 and a pipe 33, the upper end of the pipe beingclosed, forming an airchamber'. The upward extension 3 of the cap 2 hasan opening 34, which is connected with the opening 19 in the cap 15 byapipe 3 5, supporting a check-valve 36 near its upper end. \Vithin thetube is located a weight 37, having a packing-ring 38 placed upon itsupper end. A cuppacking 39 and a disk-packing 40 are held in contactwith the weight by a bolt 41, passing through the part-s, receiving anut 42 on its projecting ends. When their parts are in their normalposition, they appear as shown at Fig. 6, water being admitted into thechamber 32, holding valve 23 against its seat by the pressure of thewater inthe mains, thereby preventing the'water entering the tube. Bymoving the valvestem into the position shown by Fig. 7 the valve 23 willbe opened and the valve 24 closed by the pressure of the rear end of theThis allows the water to pass through the opening 12 in the head 7 intothe tube, and the pressure of the water from the mains will force theweight 37 up until the packing 38 comes in contact with the cap 2,thereby preventing the ingress of any more water While valve 24 isclosed by the seat bearing against it.

-Upon returning the valves to their normal positions by releasing theseat from the end of the valve-stern the inlet of the Water Will be cutoff by the pressure from the mains acting on the back of valve 23, andthe weight 37 will force the water out of the tube in an even regularflow without noise through the opening 29 in the head 8, through thedischarge-opening 20, into the bowl of the closet. The opening being ofless section than the other passages between the weight and opening 20,the weight in descending gives sufficient force to the water to back itup in pipe 35, through the opening 19, causing the checkvalve to closeafter a small portion of the water has passed it. This water goes overinto the tube on top of the weight and remains there until the nextoperation. When the weight ascends during the next operation, this waterthat was on top of the weight goes over in the pipe and down in thebowl, thereby dampening it and preventing excrement adhering to thebowl.

The water that ascends the pipe as far as the check-valve remains thereuntil the weight is down. Then it flows into the bowl gradually,replacing the loss in the trap caused by siphonage by the soil fallingdown the soil-pipe, resetting the siphon. A sufficient flow of water canbe had for rinsing the bowl after slops have been dumped in it bydepressing the seat only part way, thereby obtaining a flow of waterwithout raising the weight, and thus obviating the use of a full tank ofwater. This is illustrated in Fig. 8.

The tube and connections are fastened to the back of a plank, if woodwainscoting is used, or marble, if marble is used, or to a perforatedcast-iron slab, if tiling is used, as actual demonstration shows that itis perfectly safe to plaster or tile over it,as a register-face placedon the wall around cap 15 ed to the lower end of the tube.

To the face of the plank or wall 43 is secured the seat 46 and cover 47for a bowl 48. These parts are connected by a hinge consisting of aplate 49, secured to the plank or face of the wall 43, said plate havingears 50, and a plate 51, secured to the rear end of seat, havingvertically-extending ears 52. Two arms 53 have a pivotal connection withthe ears 50 on plate 49 by a rod 54, extending through the arms and ears50 and 53; and the aforesaid arms have a pivotal connection with theears 52 on plate 51 by pins 55, which have plates 57 on the inner ends,which screw to under side of lid 47, thus forming a pivotal connectionbetween the seat, cover, and

arms. The arms 53 are provided with extensions 58, whlch engage withangle extensions on plate 51 at rear end of seat, thereby forming astifi": joint to prevent the free end of seat from dropping when therear end rests against the Valve-stem. This combined seat and cover arelocated above the bowl 48 and one-half inch above it at the rear end, inthe manner as set forth, in order that when weight is applied to thefree end of seat it will not come in contact with the bowl, but whollysupported by its hinge connection to the face of the wall 43 and therear end seat resting against the Valve-stem. This closes valve 24 andgives a solid support for the seat, as plate 51 has an angle projectingover the rear end of seat to engage the valve-stern. This weight 011 thefree end of seat makes the seat strike inward with an are having rod 54for its pivotal 'point, and the stroke being only three-eighths of aninch there is no friction. This same stroke opens valve 23 against themain pressure, but the movement of closing valve 24 and opening valve 23is so gradual that it permits water direct from the mains to rushthrough before 24 is closed, and thereby forming a forewash to preventexcrement adhering to the bowl. This action and the return of the waterfrom over the weight gives two intermediate washes that are Veryessential to cleanliness of the bowl and have been much sought after.Releasin g the pressure from the free end of the seat the spring raisesthe seat and the pressure from the mains cuts off the water by valve 23and flushes the bowl by valve 24 opening simultaneously, thereby leavingthe tube empty until the next operation. The cover 47 is free to beraised independently of the seat or with the seat-pins 55, forming thepivot, or the whole can be raised entirely from a close proximity of thebowl up against the wall by using rod 54 as the pivot. This is a featuremuch sought after, as repairs do not necessitate the removal of theseat, or an accident to the bowl does not require the purchase of a newseat or any work upon it.

I claim as my inVention- 1. In a water-closet, the combination of a tubehaving an open contracted upper end, a movable weight located within thetube, a discharge-chamber a valve arrangement for admitting water intothe tube below the weight and allowing water to escape into thedischarge-chamber and a stand-pipe connection between the upper end ofthe tube and discharge-chamber,said pipe supporting a checkvalve.

2. In a water-closet, the combination of a suitable support, a valvearrangement, a bracket secured to the support, a seat, a bracket securedto the seat, links pivotally connecting the two brackets, and a coverpivotally connected to the seat, the seat resting against the valvearrangement.
